Proposition O was created to help the City of Los Angeles comply with the Total Maximum Daily Load (TMDL) requirements under the Clean Water Act. In this study, the effectiveness of the Proposition O projects in Los Angeles River watershed was examined to show whether it achieves the goal of meeting water quality standards. Our analysis shows the most effective single project will remove at most 2% of pollutant loads from Los Angeles River Watershed and will not achieve TMDL compliance, although several projects can make important contributions to achieve compliance. The ranking results show that the projects that treat the runoff from the largest drainage area have the greatest impact on the water quality of Los Angeles river.
O号提案旨在帮助洛杉矶市遵守《清洁水法》规定的总最大日负荷（TMDL）要求。在本研究中，对洛杉矶河流域O号提案项目的有效性进行了评估，以确定其是否实现了达到水质标准的目标。我们的分析表明，最有效的单个项目最多只能去除洛杉矶河流域2%的污染物负荷，无法实现TMDL合规，尽管有几个项目可为实现合规做出重要贡献。排名结果显示，处理最大排水区域径流的项目对洛杉矶河水质的影响最大。
